The specific heat of a metal is determined by heating the weighed metal, adding it to water in a calorimeter, and measuring the temperature change. The specific heat of water is 4.180 Joules per g per ºC. The data collected are as follows: Grams of water in the calorimeter 47.32 Grams of metal 16.34 Initial temperature of metal 100.32 Initial temperature of water (ºC) 22.31 Maximum temperature of water after metal is added (ºC) 23.92 Calculate the following: Specific heat of metal (keep two decimal places)

5. The formula for the ordinary least squares slope parameter in a simple linear regression model Suppose the simple linear regression model is given as $y = \beta_0 + \beta_1x + u$. Assuming $\sum_{i=1}^{n} (x_i - \bar{x})^2 > 0$, which of the following best represents the ordinary least squares (OLS) slope parameter $\hat{\beta_1}$? Where: $\hat{\rho}_{xy}$ = the sample covariance between $x_i$ and $y_i$. $\hat{\sigma}_{x}$ = the sample standard deviation of $x_i$ $\hat{\sigma}_{y}$ = the sample standard deviation of $y_i$ $\circ \frac{\hat{\rho}_{xy}}{\left(\frac{\hat{\sigma}_x}{\hat{\sigma}_y}\right)}$ $\circ \frac{\hat{\rho}_{xy}}{\left(\frac{\hat{\sigma}_y}{\hat{\sigma}_x}\right)}$ $\circ \frac{\hat{\rho}_{xy}}{\left(\hat{\sigma}_x \hat{\sigma}_y\right)}$ $\circ \hat{\rho}_{xy} \left(\frac{\hat{\sigma}_x}{\hat{\sigma}_y}\right)$ <0 >0 Suppose you collect data and $x_i$ and $y_i$ are positively correlated in your sample. You know that after using OLS to estimate the simple linear regression model, $\hat{\beta_1}$ must be

Assume you purchased a $1,000, 10-year corporate bond with a 5% interest rate. If interest rates in the marketplace rise to 7%, this means buyers can get around 7% on similar quality new bonds. If this happens, you will likely be able to sell your 5% bond at a premium.
